Hi-RelMilitary / Aerospace DC‑DC converters

OPERATIONAL

• Fixed switching frequency • No opto-isolators • Parallel operation with current share on MQFL • Remote sense • Clock synchronization • Primary referenced enable • Secondary referenced enable on MQFL • Continuous short circuit and overload protection with auto-restart feature

• Input under-voltage and over-voltage shutdown • Output voltage trim range (MQHL, MQHR & MQBL) +10% to -10%

DESIGN PROCESSHi-Rel series converters are:

• Designed for reliability per NAVSO-P3641-A guidelines

• Designed with components derated per:◊ MIL-HDBK-1547A◊ NAVSOP-3641A

MECHANICAL

• QorSeal packaging • Industry standard footprint for MQFL & MQME • Multiple mounting configurations & lead form options • Gold plated nickel barrier finish on an extruded aluminium case

IN-LINE MANUFACTURING PROCESS • AS9100 and ISO 9001:2008 certified facility • Full component traceability • Temperature cycling • Constant acceleration screening • 24, 96, 160 hour burn-in • Three level temperature screening

QUALIFICATION PROCESSHi-Rel series converters are qualified to:

• MIL-STD-810◊ consistentwithRTCA/DO-160

• SynQor’s First Article Qualification◊ consistentwithMIL-STD-883

• SynQor’s Long-Term Storage Survivability Qualification

• SynQor’s on-going life test • SynQor's element evaluation for HB & ES Grade

SPECIFICATION COMPLIANCEHi-Rel series converters (with Hi-Rel filter) are designed to meet:

• MIL-HDBK-704 • RTCA/DO-160 Section 16, 17, 18 • MIL-STD-1275 (B, D) • DEF-STAN 61-5 (Part 6)/(5, 6) • MIL-STD-461 (C, D, E, F) • RTCA/DO-160 (E, F, G) Section 22

High-reliability, Field Proven DC-DC Converters for Military/Avionics ApplicationsThe MilQor series of high-reliability DC-DC converters brings SynQor’s field proven high-efficiency synchronous rectifier technology to the Military/Avionics industry. SynQor’s innovative QorSeal™ packaging approach ensures survivability in the most hostile environments. Compatible with the industry standard format, these converters operate at a fixed frequency, have no opto-isolators, and follow conservative component derating guidelines.

* Converters may be operated continuously at the highest transient input voltage, but some component electrical and thermal stresses would be beyond MIL-HDBK-1547A guidelines.

† 80% of total output available on any one output.

Hi-RelEMI filters are available with passive components only, or with additional active circuitry that provides surge/spike suppression, soft start in-rush limiting, reverse-polarity protection, and enable signal pass-through. They also are available in standard and extended input voltage ranges.
